Two months before the release of the Creators Update, Microsoft has announced a new feature included in the upcoming upgrade.
PC owners who run the Creators Update will get picture-in-picture support. Microsoft is calling the feature “Compact Overlay". It will be available for all app developers making Universal Windows apps, and it'll be available in built-in apps like Movies & TV or Skype. The feature essentially allows you to watch something like a Skype video call in a window that can hover above another window or app you may be using.
Microsoft is currently testing Compact Overlay as part of the latest Windows 10 build 15031, which the company made available for fast ring insiders on 8 February. Microsoft also revealed Wednesday that Windows 10 Creators Update is feature-complete, meaning all of the new features are finished - apart from any bugs that may be found - for the update's official release coming to consumers this spring.
Microsoft will make the Windows 10 Creators Update available to new and existing PCs in April.
